Application filed April l0, 1&22,

To (all cti/0my may concern.'

Be it lrnoivn that l, NAroLoN PiiQUnrrn,

a citizen olj the United States, residing at Detroit, in the county oi lli/Tayne and State 5 of iiichigan, have invented a new and use- Ful llubricator. of Which lthe following` is a specification.

This :invention relates to lubricators, and particularly to oiling devices such as are used on springshackles and similar bearings of motor vehiclesy in which the lubricant is conducted through channeled passan'es to the bearing surfaces.

The principal object oit' the present invention is to provide for safeguarding the lubricant passages against liability to become stopped or clogged lwith sediment7 through the provision of means to erlect the clearing of the lubricant passa-ges of any accumulated sediment automatically with each operation of filling the device with lubricant, thus facilitating and assuring'- the positive delivery oi the lubricant to the bearing surfaces.

lin attaining this object.` the invention con` templates the employment in connection with a bearing spindle having a longitudinal channel communicatingwith an oil cup, of a rod or Wire prod extendingr at one end into said channel and having; its opposite end portion return-bent and helically coiled to `term. a compression spring' Within the oil cup. and an adjustable cap for closingsaid cup and coniiwessing;- said spring. whereby movement ot the cap in opening,- and closing the cup causes movement of the spring' and a. resultant movement of the Wire in'od longitudiimtll'y1 of the Channel which tends to prevent clogo'ing oit the latter.

preferred embodiment of the invention is illustrated in the accompanying; drawing, in which.

itin. l is a vien` in elevation of a bea-ring spindle equipped with the lubricator em- .iodyiugj my invention Fig. 2 is longitudinal sectional view on dashed lines 2--2 olf l.

Fig. 3 is an enlarged view in elevation of the integrally formed Wire prod and actuatin;r coiled spring.

Referring); to the drawings, l indicates a bearin shaft or spindle having' an enlarged shouldered extension 2 at one an axial bore 3 forms the chamber or' an dinally oit the passage end in which Serial No. 551,235.

oil retainingcup The Wall ot the cup 4i adjacent the slionldcr 2 provided Ywith an oil inletl opening 5 and this opening' as Well as the outer end oil the cup is normally closed by a sleeied cap 6 which 'freely embraces the cup i abutting at its capped end against the outer end of said cup. rlFhe cap is retained agai 1 disengagement with the cup but is permitted to be moved rotatively and lo-ngitudinallj` "thereoi to uncover the oil inlet opening; by means of a stud or screvv 7 anchored in the Wall oi"- the cup ano engaging with a. right-angled slot 8 in the sleeve oi the cap in the manner of an ordinary bayonet lock.

The body or the spindle is formed with a` longitudinal oil communicat-inn` channel or passage 9 which communicates at one end With the oil cup 4, and at its opposite end Wita the surface of the spindle through a radial slot l0, and extending' through said passage is a ivi re prod ll one end oi"I which is bent laterally to engage in said slot and the opposite end of said Wire is return-bent relative to the body portion and helically coiled to form a. compression spring, as shown in Fig. 3. The inner tree end of the spring seats upon the bottom oiI the oil cup, and the outer end ot said spring and prod abut against the inner face of the cap 6.

The length et the spring is somewhat greater than the depthoi. the oil cup, hence When the cap is in its normally closed positioni as shownj the spring is compressed and the prod correspondingly extended loin/itin and slot to the iimit ofi'l its `inward movement. ln this position a partial rotation oi the cap, such as to enthe angular portion the enter end of the slot 8 with the screnv 'i'. vfill lock said cap against outward movement b v the influence of the spring'. A. reverse rotative movement of the cap Will release it to undergo outward movement limited by enganement of the inner end ot said slot with said screw, as indicated by dotted lines in Fig'. l, in which position the oil inlet opening Will be uncovered and the expansive action of the spring will have shifted the Wire prod in a corresponding direction and distance in the oil conducting passage.

.it will be clear from the foregoing that upon each operation or' unsorevving the oil inlet opening to intiocluce oil to the eup and upon closing said opening thiough manipulation olf the cap, movement Will automatically be impaitecl to the Wie prod in a Vmanne/1 tending to prevent clogging ofthe oil passages, and to Yaeilitate feeding el the oil to the bearing surfaces.

What l claim is:

l. A lubiieatoif comprising anv oil cup having an outlet passage, aclosuie oi said cup movable longitudinally theieol, a Wire prod extending at oney end through said passage and i'esiliently formed at its opposite end and stressed between said cup and closure,
